Bike riding - Beating uphill sections

Uphill sections are, for me, some kind of double edged sword: they're hard to beat, get me tired and slow, but after an uphill there's a delightful downhill section where I can stretch and  my legs and drink some water.

The way I go through these sections has a great impact on my performance during the ride and how tired I get after it. So far, I found two ways of doing this:

1 - Sit and keep the cadence you feel confortable with (number of revolutions per time, rhythm) even if it means using lower gears and go slower;
2 - Or lift my butt and use higher gears (keeping the right cadence too).

The main difference I find between these two is what part of me feels more tired: my heart (first method) or my legs (second method).

The first method is ideal for long uphill sections where endurance is required. Since I keep sit, all the effort goes to keep my rhythm. For best use, you should keep your body still (except your legs of course) and follow a straight line.

The second method is best for doing uphill sprints. This way I can use the weight of my body by rocking my hip in each pedal stroke. The reason for using higher gears in this method is because each stroke is much stronger than the first method ones. If you use low gears in method 2,  you will feel each stroke being wasted, because the pedal will go down too fast and recoveries will be very hard. I recommend shifting up one or two gears.

Final comment on bike riding:
Training is the key to learn more. Even though effort management and technique are important, knowledge and stamina need training to improve. For me, living in such beautiful place, not far from the sea, is a privilege and a pleasure to be able to ride my bike around here. I guess I'll miss this for the next few months.

Personal Status Update + a personal cheesy but caring message

In little more than a month I will be leaving my country to stay a few months working in an investigation project. Which sounds pretty cool right?

Well, on one side, of course. On the other, I have had little time for preparations since I am working to make some money during the day and only come to the PC at night.

Days go by without me noticing I'm running out of time for preparing my work abroad. I would like to  keep writing about cars, and bike riding, and Linux stuff I learn here and there... there are a few drafts of ideas I have for blog posts, but there is something much more important now.

When I look back at my life, I know I have not always been the disciplined person I wish I was (otherwise this blog would have much more contents, of course). I have not always been helpful to others when I should have, but more importantly, I have not been up to the person I love the most: my girlfriend.

Even though I am still a klutz, I am getting better over time because of her. And even though I still fail her sometimes, I wish we can both be happy together. So this post is dedicated to her.

To anyone who might read this: remind yourself who are the most important people in your life and make sure you tell them.

Ford and the small turbocharged engine

   Diesel engines have received a lot of attention lately: smaller (1.4 liter) blocks, turbocharged, low consumptions and emissions... No wonder people in Portugal buy, mostly, small turbocharged diesel cars (and diesel is also cheaper than petrol).

   However, those of us who are, and will always be in love with petrol engines, there was not much of a choice: either a small, sluggish high compression engine, but somehow easy on fuel consumption (such as "my" VW Polo 1.0 MPI), or a larger petrol engine, which was not so easy on gas mileage...

   Finally some motor companies decided to dedicate to petrol engines: Ford was recently awarded with the 2014 International Engine of the Year for its 1.0 EcoBoost engine!

  The 3 cylinder, 100, 125 or 140 hp turbocharged EcoBoost engine features low fuel consumption and still keeps a good performance, hence being so popular in Europe (1 in each 5 Fords sold in Europe had this engine), according to Autoblog (article in Portuguese). The turbocharger in this engine is running 1.6 bar, an impressive number if you think about the 1.1 bar value in a 2013 Impreza (source here).

   This reminds me of a 180 hp 1.4 liter engine created by FIAT. However, the popularity of this Ford 1.0 might be boosted by the increasing fuel price, and economical crisis in Europe.

  Whatever the reason for its popularity is, I hope this engine marks the beginning of an era where turbochargers increase the efficiency of small engines, end the boredom of small slow petrol engines, and brings back the popularity of small petrol engines over diesel ones.

   Let the forced induction begin.
